It's a shame, in the novel Elma really steps in here and haggles the price for our inexperienced MC.
It makes complete sense for the limited panel space but I hope they show how useful she is all the time instead of just space elf waifu. (She pretty much carries every important social interaction in the novel)
Semen plays a huge role. Normally races can only be with their own to have offspring, but Hiro has a special version that is stronger than the basic contraceptive and could even go crossing race borders.
But please remember, fucking a elf is bestiality then by your logic. Because race in space isn't just white, black, etc. It's pretty much every humanioid species that has differences between themselves.
@dudewithmagic They did show a few chapters back how our MC pretty much looked for Elma to decide if a offer is yay or nay so they do try to show it. Lessee how they continue from here.
